how far out is the final approach course valid?

What is a final approach course in aviation?

Final approach course FINAL APPROACH COURSE- A bearing/radial/track of an instrument approach leading to a runway or an extended runway centerline all without regard to distance. - The final approach course alignment with the runway centerline exceeds 30º. Final - Final approach course, aligned with landing runway

Can pilots report established on the final approach course?

Therefore, pilots may be requested to report established on the final approach course.

What are the requirements of a final approach controller?

Other requirements are: radar availability, nonintersecting final approach courses, precision approach capability for each runway and, if runways intersect, controllers must be able to apply visual separation as well as intersecting runway separation criteria.

What happens after you pass the final approach fix?

After passing the final approach fix on final approach, aircraft are expected to continue inbound on the final approach course and complete the approach or effect the missed approach procedure published for that airport. ARTCCs are approved for and may provide approach control services to specific airports.

How far out is final approach?

The final phase is often the last 5 miles when the airplane is aligned with the runway and is descending toward it. Q: I was sitting next to a pilot on a commercial flight, and he said that we must be 6 miles from touchdown when he heard the landing gear engaged.

How far out is glideslope reliable?

Localizer and glideslope signals have limited ranges. At most, reliable signals extend as far as 18 nautical miles or so, but that's only for localizer guidance within 10 degrees of the course centerline.

How high should you be on final approach?

The associated point used on the final approach is typically 500 feet aal or 1,000 feet aal depending on the operator in question. Some operators may specify both depending on the conditions e.g. 500 feet aal may be used during VMC but this must be increased to 1,000ft aal during IMC.

What is the 3 6 rule?

For larger aircraft, typically people use some form of the 3/6 Rule: 3 times the altitude (in thousands of feet) you have to lose is the distance back to start the descent; 6 times your groundspeed is your descent rate.

How far away can you pick up ILS?

ILS Category I: Provides for approach to a height above touchdown of not less than 200 feet, and with runway visual range of not less than 1,800 feet. ILS Category II: Provides for approach to a height above touchdown of not less than 100 feet, and with runway visual range of not less than 1,200 feet.

What if glideslope fails on ILS?

If you fail your glide path indicator (put a sticker on it) and you are - for any reason - not visual with the runway at your minimums passing the DTL go around, do not change back to the ILS.

What speed should you descend at?

The 60:1 Rule, Explained And it's not even that hard. There are more applications of the 60:1 rule in aviation than we could possibly cover here, so we'll stick with descent planning. After all, nobody intends on diving their plane at 2,000 feet per minute to make it to pattern altitude.

How difficult is it to land a plane?

The normal sink rate of an aircraft on landing is two to three feet per second; when a pilot lands at seven to eight feet per second, it will feel harder than normal. Pilots have been known to report it as a hard landing, Brady explained, even though the landing was within the prescribed limits.

What speed is VREF?

VREF usually is defined by the aircraft operating manual (AOM) and/or the quick reference handbook (QRH) as: 1.3 x stall speed with full landing flaps or with selected landing flaps.

When should a pilot start descent?

As an example, if the airplane is flying at 30,000 feet the pilot should start the descent at 90 miles. Once the airplane is closer to the airport and the instrument landing system (ILS) can be used, the 3-degree descent is more finely tuned to touchdown.

How do you use the 1 60 rule?

1:403:40You are three miles off track with 30 miles to go therefore 2 x 3 miles off track gives you aMoreYou are three miles off track with 30 miles to go therefore 2 x 3 miles off track gives you a correction angle that is a further 6 degrees to the right.

How many feet is a minute descent?

In aviation, the rule of three or "3:1 rule of descent" is a rule of thumb that 3 nautical miles (5.6 km) of travel should be allowed for every 1,000 feet (300 m) of descent. This assumes a normal jet airplane, at idle thrust, speed of Mach 0.74 to 0.78, and vertical speed of 1,800–2,200 feet per minute.

Somewhere in South Central Wisconsin, An Airplane Buzzed By

You are being radar vectored to the straight-in VOR Runway 18 approach at Dane County Regional-Truax Field in Madison, Wisconsin. Madison Approach currently has you on a right base leg, 10 DME northwest of the VOR. The approach controller says, “Cessna 30D,”

The AIM Read Back

What is the required read back for this clearance? According to the AIM, you need to read back “the numbers”, plus an acknowledgment you have been cleared for an approach. In this example, you would read back the TAC in PTAC. This includes your assigned heading, altitude, and that you have been cleared for an approach.

My Read Back Technique

Here’s how I would read back this clearance. By the way, my technique is not original. It’s used by pilots around the world.

Why the AIM Guidance Falls Short

This is why I think only saying, “Cleared for the approach” is so anemic. It gives ATC no chance to fully check how you plan to intercept the approach. It doesn’t even provide assurance you are going to fly the correct approach.

What You Can Do with this Information

1. ATC will always give you a final approach clearance using the PTAC format. It’s something you can hang your hat on, especially if you struggle with absorbing a complex clearance.

Do altimeters agree with GS intercept points?

Whatever you do, make sure the altimeter agrees when you are at the GS intercept point or you could be in for a really bad day. And be aware of the presence of false glideslopes and how they occur.

Is there an altitude above or below?

Almost every altitude on every procedure is an "at or above altitude". The cases where there is an "at" altitude or even a "below" altitude exist, and require special attention, but for most procedures at most airports, "at or above" is the rule. If ATC needs something different they will have to tell you.

Do you have to be above 4000 to be ATC?

If ATC needs something different they will have to tell you. If they clear you to "maintain 4000 until established", then yes, you have to be at 4000, not above 4000, but once you're established, then all of the subsequent altitudes are "at or above".

Do you have to stay at 4000?

So, stay at 4000 if you like, or descend to the published altitude, or something in between.

What is the final approach fix?

The Final Approach Fix is the point where the Final segment of a Non-precision Approach procedure begins.

Which segment of the LOC procedure has a steeper descent angle compared to the ILS approach?

The final approach segment of the LOC procedure has a steeper descent angle compared to the ILS approach.

What is the FAF point?

Since the FAF is the last point before the final descent of your approach, it is important that you overfly this point at the right altitude, speed and, centred laterally.

How high can you fly the FAF?

On the right chart, from the picture above, the FAF is located over the MA locator and you must overfly it at an altitude of 3400 feet.

Why do you have to identify the position of this fix during your Approach briefing?

You have to identify the position of this fix during your Approach briefing because it is the most important point of your Non-Precision Approach.

Is vertical profile applicable to ILS procedure?

So, one vertical profile is applicable to the ILS procedure and one to the Localizer Procedure.

Is FAF only applicable to precision approaches?

The FAF is only applicable to Non-Precision Approaches however, many Pilots believe that it is applicable to Precision Approaches as well.

When landing at airports with approach control services and where two or more IAPs are published, pilots will be?

When landing at airports with approach control services and where two or more IAPs are published, pilots will be provided in advance of their arrival with the type of approach to expect or that they may be vectored for a visual approach. This information will be broadcast either by a controller or on ATIS. It will not be furnished when the visibility is three miles or better and the ceiling is at or above the highest initial approach altitude established for any low altitude IAP for the airport.

What is approach control?

Approach control is responsible for controlling all instrument flight operating within its area of responsibility. Approach control may serve one or more airfields, and control is exercised primarily by direct pilot and controller communications. Prior to arriving at the destination radio facility, instructions will be received from ARTCC to contact approach control on a specified frequency.

What does ATC expect from pilots?

When crossing altitudes and speed restrictions are issued verbally or are depicted on a chart, ATC will expect the pilot to descend first to the crossing altitude and then reduce speed. Verbal clearances for descent will normally permit an uninterrupted descent in accordance with the procedure as described in paragraph b above. Acceptance of a charted fuel efficient descent (Runway Profile Descent) clearance requires the pilot to adhere to the altitudes, speeds, and headings depicted on the charts unless otherwise instructed by ATC. PILOTS RECEIVING A CLEARANCE FOR A FUEL EFFICIENT DESCENT ARE EXPECTED TO ADVISE ATC IF THEY DO NOT HAVE RUNWAY PROFILE DESCENT CHARTS PUBLISHED FOR THAT AIRPORT OR ARE UNABLE TO COMPLY WITH THE CLEARANCE.

What happens if a speed restriction is published at Leoni?

If a speed restrictions is published at Leoni, the aircraft will slow to comply with the published speed.

What does "cleared to a waypoint" mean?

When cleared to a waypoint depicted on a STAR, to descend from a previously assigned altitude at pilot's discretion to the altitude depicted at that waypoint.

When making an IFR approach to an airport not served by a tower or FSS, should you broadcast your intentions?

When making an IFR approach to an airport not served by a tower or FSS, after ATC advises “CHANGE TO ADVISORY FREQUENCY APPROVED” you should broadcast your intentions, including the type of approach being executed, your position, and when over the final approach fix inbound (nonprecision approach) or when over the outer marker or fix used in lieu of the outer marker inbound (precision approach). Continue to monitor the appropriate frequency ( UNICOM, etc.) for reports from other pilots.

When is radar service terminated?

Whether aircraft are vectored to the appropriate final approach course or provide their own navigation on published routes to it, radar service is automatically terminated when the landing is completed or when instructed to change to advisory frequency at uncontrolled airports, which ever occurs first.
